Evidence Law: Hearsay, Expert Opinion, and Documentary Evidence
Exam Snapshot
Admissibility determines what information a judge or jury can consider during a trial. While hearsay is generally excluded to ensure reliability, exceptions apply, such as dying declarations. Expert opinion is admissible only when the court requires specialized knowledge, and documentary evidence follows the 'Best Evidence Rule,' prioritizing original documents over copies.
Core Concept
- Hearsay Evidence: An out-of-court statement offered to prove the truth of the matter asserted. It is generally inadmissible because the declarant cannot be cross-examined.
- Expert Opinion: Testimony or reports provided by individuals possessing specialized knowledge (science, arts, law, or technical skills) that aids the court in reaching a conclusion. The expert must be qualified and relevant.
- Documentary Evidence: Written records, including private and public documents. The law prioritizes primary evidence (the original document) over secondary evidence (copies or oral testimony about the document).
Nepal Law Anchors
- Evidence Act 2031 (Nepal): Governs the admissibility of oral, documentary, and expert evidence.
- Sections 18-20: Provisions regarding documentary evidence, including the requirement for primary evidence.
- Section 23: Admissibility of expert opinion.
- Section 27: General rule regarding the exclusion of hearsay.
Confusable Terms
| Term | Focus | Admissibility Rule |
|---|---|---|
| Hearsay | Out-of-court statement | Generally inadmissible |
| Expert Opinion | Specialized knowledge | Admissible via court-recognized expert |
| Documentary | Written record | Best Evidence Rule applies |
MCQ Traps
- The "All Hearsay is Bad" Trap: MCQs often present scenarios where hearsay is allowed. Remember that exceptions, like dying declarations or admissions, are admissible.
- The "Any Expert" Trap: Just because someone is a professional does not make them a court-recognized expert for a specific case. The expert must be qualified in the specific technical field relevant to the dispute.
- The "Original Only" Trap: While the Best Evidence Rule prefers originals, secondary evidence IS admissible under specific circumstances, such as when the original is lost, destroyed, or in possession of an adverse party.
Example
In a murder trial, a neighbor claiming, 'Someone told me they saw the accused at the scene,' is hearsay and generally inadmissible. However, a forensic pathologist testifying that, 'Based on the wound pattern, the death was caused by a specific type of blade,' is expert opinion and is admissible. If the pathologist presents their signed report, that is documentary evidence.
Memory Hook
- Hearsay: Hear it? Don't use it. (Unless it's an exception!)
- Expert: Need a skill? They fill the bill.
- Documentary: Go to the source (Primary Evidence).
Quick Revision
- Hearsay is out-of-court; its main defect is lack of cross-examination.
- Expert opinion is limited to scientific, technical, or specialized areas.
- Primary evidence is the original document; secondary evidence requires a valid justification for its use.
- Admissibility is a question of law; weight (probative value) is a question of fact.
- Dying declarations are a critical exception to the hearsay rule.
